@aswadd ..you're having the same problem that I had in the past by integrating zcm settings inside the configuration arc.ini files, try to eliminate fazip configuration, decompression should be successful.
Now I am in the company to update a management software, but in the evening I think to solve the problem, in order to integrate with other 30 compressors the zcm without this going at odds, especially with fazip and the classic error : "ERROR: write error (disk full?) in compression algorithm lzma:mfbt4:d1m".
